OVR Gaze Event Trigger not triggering script events

Hello,
I am new to developing for Oculus. I have a canvas with a menu button. I have attached the Over Gaze Event Trigger to it. I set up the script to run my functions from my VRButton scripts, which changes the BackgroundImage color. However, when I run the program and use transform to move my Gaze Pointer Ring over the MenuButton and I click on the game scene, nothing happens. Please help, I have been going over this tutorial and I can't find any difference between mine and his.

Here is a zip of my project. If there is a better way of sharing it, let me know.

This is my VRButton script.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class VRButton : MonoBehaviour {
7.  
8.     public Image BackgroundImage;
9.     public Color NormalColor;
10.     public Color HighlightColor;
11.  
12.     // Use this for initialization
13.     void Start () {
14.        
15.     }
16.    
17.     // Update is called once per frame
18.     void Update () {
19.        
20.     }
21.  
22.     public void OnGazeEnter()
23.     {
24.         BackgroundImage.color = HighlightColor;
25.     }
26.  
27.     public void onGazeExit()
28.     {
29.         BackgroundImage.color = NormalColor;
30.     }
31. }
